大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

Coiban Mastuff Bat

The Coiban Mastuff Bat (Molossus coibensis) is a small free-tailed bat in the family Molossidae, named for Coiba Island off the Pacific coast of Panama, where specimens were first collected. Members of the genus Molossus are robust, fast-flying insectivores adapted to open-air foraging above the forest canopy and over water, characterised by narrow wings and a tail that extends beyond the patagium (wing membrane). Molossus coibensis inhabits lowland tropical forests and adjacent open habitats in Central America and northwestern South America, with confirmed records from Colombia, Ecuador, Venezuela, and Panama, indicating a distributional range that extends well beyond its type locality on Coiba Island. Like other mastiff bats, it roosts in crevices within buildings, rock faces, and hollow trees, emerging at dusk to pursue aerial insects at speed. The species feeds primarily on large beetles, moths, and other night-flying insects, typically hunted high above the forest. It is assessed as Least Concern by the IUCN based on its relatively wide range and tolerance of modified habitats. Molossus coibensis was long treated as a subspecies of Molossus molossus before being recognised as a distinct species based on morphological and molecular evidence. Ecological and life-history data specific to this taxon remain limited.
